I like Vette because it is an optimistic character, say what's on her mind, and her replies are funny.
Next companion who want to be is Elara Dorne.
I don't like Quinn Malave, even if it have a prrety face, is the weakest healer character of all companion that are healers.
P.S. I gave the collar from the Vette neck down when we entered in the first cantina that is on the imperial fleet because I don't wanted to treat her like a slave, but as a reliable companion that helps me, even though I have10k DS.
